heat networks

Energy debt remains one of the biggest challenges facing the utilities sector today. The conversation is no longer just about recovering unpaid bills.
Headlines Domestic energy debt is expected to reach £7 billion, while more than three million customers are already in debt or arrears. The focus is increasingly shifting from simply collecting debt to preventing it and providing earlier, more meaningful support to those who need it most. At the Energy UK conference, earlier this week, speakers warned that energy debt reached £6 billion in 2026 and could rise further without coordinated action from industry and government.
But while energy suppliers continue to explore how data, technology and customer support can work together, many heat networks already have access to the tools needed to identify risk earlier and intervene more effectively.
Increasingly, it is about understanding vulnerability, identifying risk earlier, and providing meaningful support before financial difficulties escalate into crisis.
While affordability is often discussed in terms of energy prices, the reality is much more complex. Behind every account is a person, family or household facing their own circumstances. Financial pressures can often sit alongside health conditions, caring responsibilities, bereavement, digital exclusion or major life changes.
The challenge for providers is that vulnerability is not always visible. Many customers struggle in silence, delaying requests for help due to embarrassment or uncertainty about what support is available. That means organisations cannot rely solely on residents coming forward. Instead, they need smarter ways to identify when support may be required.
This is where residential heat networks have an opportunity and can continue to lead.
For many years, smart metering has been associated primarily with accurate billing and operational efficiency. While these benefits remain important, the value of smart data extends far beyond meter readings.
Heat network operators often have access to detailed consumption, payment and billing information that can help identify potential signs of vulnerability much earlier. Patterns such as recurring low credit balances, self-disconnection from pay-as-you-go services, increasing debt levels or unusually low heat consumption during colder periods may indicate that a resident is struggling.
Used responsibly, this insight allows providers to move from reacting to debt after it occurs to proactively engaging with residents before a situation becomes unmanageable.
One area we do have control over is how we use data and technology to recognise potential vulnerability sooner. Combined with well-trained customer support teams, these insights can help ensure the right conversations happen at the right time.
There is another important distinction between residential heat networks and traditional energy suppliers.
Gas and electricity suppliers are regulated directly by Ofgem and accountable through supplier licence conditions. While these protections are essential, the relationship can sometimes feel transactional.
Residential heat networks are also subject to Ofgem compliance, however there is a golden thread to housing that really makes a big difference.
Residential heat networks often operate within communities where building owners, housing providers and managing agents have a direct and ongoing interest in resident wellbeing. Their success is not just measured by revenue collection or operational performance. It is also linked to resident satisfaction, comfort, tenancy sustainability and community outcomes.
This creates a more joined-up approach to support.
Housing providers frequently have a deeper understanding of residents' circumstances, whether that involves financial hardship, accessibility needs, health conditions or changing personal situations. When this knowledge is combined with heat network consumption and billing data, opportunities emerge to provide earlier interventions and more personalised assistance.
The introduction of stronger consumer protections across the heat network sector will only strengthen this focus further. Alongside regulatory oversight, many social housing residents already benefit from the protections offered by the Housing Ombudsman, while wider housing reforms continue to place greater emphasis on transparency, accountability and resident outcomes.
The utilities sector is increasingly recognising that preventing debt is about more than payment plans and collections processes. It requires better communication, earlier engagement and a genuine understanding of customer circumstances.
The most effective organisations are those that take a human approach. They communicate empathetically, make support easy to access and create customer journeys that reflect the realities of people's lives.
For residential heat networks, this represents a significant opportunity.
For years, much of the conversation has naturally focused on efficiency, billing accuracy and compliance. These remain critical foundations. But the next stage of the sector's evolution is about something bigger: the people behind the data.
Energy is not simply a utility service. It plays a vital role in how safe, comfortable and secure residents feel in their homes. By using data intelligently, delivering proactive support and embedding strong consumer protections, heat networks can help create warmer homes, healthier communities and better outcomes for residents. Just like our mantra at Switch2 - Keeping customers warm, sustainably.
As the wider energy sector searches for better ways to support vulnerable customers and tackle rising levels of debt, residential heat networks are well placed to demonstrate what good looks like. The goal is to help residents feel supported, resilient and able to thrive in the communities they call home.
